Lub metallurgical zog ntawm cov hlau ntshiab yog hais txog cov yam ntxwv kev ua tau zoo muaj feem xyuam rau metallurgy thiab metallurgy pom los ntawm cov hlau ntshiab thaum smelting, ua, thiab siv. Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm cov khoom siv metallurgical ntawm cov hlau ntshiab:
1, Basic metallurgical zog
High melting point thiab siab thermal conductivity:
Cov hlau ntshiab muaj qhov siab melting point, uas txhais tau hais tias nws tsuas yog yaj ntawm qhov kub thiab txias.
Nyob rau tib lub sijhawm, cov hlau ntshiab kuj muaj cov thermal conductivity zoo thiab tuaj yeem hloov cov cua sov sai.
Zoo plasticity thiab toughness:
Nyob rau hauv chav tsev kub, cov hlau ntshiab muaj cov yas zoo thiab tawv, thiab tuaj yeem tiv taus qee qhov deformation yam tsis muaj tawg.
Yooj yim rau txheej txheem:
Cov hlau ntshiab yog ib qho yooj yim rau kev txiav, khoov, vuam thiab lwm yam kev ua haujlwm, uas yuav pab txo cov nqi tsim khoom thiab txhim kho kev tsim khoom.
2, Cov khoom sib nqus tshwj xeeb
Cov hlau ntshiab yog ib qho ntawm cov khoom sib nqus nrog cov khoom sib nqus tseem ceeb.
High magnetic permeability:
Cov hlau ntshiab muaj qhov sib nqus permeability siab thiab tuaj yeem xa cov khoom sib nqus zoo.
Zoo magnetic saturation:
Nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb, cov hlau ntshiab tuaj yeem ncav cuag magnetic saturation, qhov twg cov hlau nplaum induction tsis muaj zog ntxiv nrog rau qhov nce ntawm magnetic teb zog.
Hysteresis thiab remanence phenomena:
Cov hlau ntshiab yuav tsim qhov tshwm sim hysteresis thaum lub magnetic teb hloov, uas yog, qhov kev hloov ntawm magnetic induction intensity lags qab qhov kev hloov ntawm magnetic teb siv.
Meanwhile, thaum lub magnetic teb ploj mus, cov hlau ntshiab yuav tseem khaws tau ib qho residual magnetism.
3, Corrosion kuj
Cov hlau ntshiab muaj qhov zoo corrosion kuj nyob rau hauv ib puag ncig qhuav, tab sis nws cov corrosion kuj yuav txo qis hauv cov av noo lossis corrosive media ib puag ncig. Yog li ntawd, nyob rau hauv daim ntawv thov uas yuav tsum tau corrosion kuj, nws yog feem ntau tsim nyog los ua nto kho los yog alloying kev kho mob ntawm cov hlau ntshiab los txhim kho nws corrosion kuj.
4, Lwm yam khoom siv hlau
Weldability:
Cov hlau ntshiab muaj qhov zoo weldability thiab tuaj yeem txuas tau los ntawm ntau txoj kev vuam.
Kev kho cua sov khoom:
Cov hlau ntshiab tuaj yeem hloov nws cov qauv thiab cov khoom siv los ntawm kev kho cua sov, xws li ua kom nws cov tawv tawv thiab lub zog los ntawm kev quenching thiab tempering.
Kev ua haujlwm txias:
Cov hlau ntshiab tau ua haujlwm hnyav thaum ua haujlwm txias, qhov twg nws qhov hardness thiab lub zog nce ntxiv nrog kev deformation, tab sis nws cov plasticity thiab toughness txo.
Hauv cov ntsiab lus, cov khoom siv hlau ntawm cov hlau ntshiab muaj xws li nws cov khoom siv hlau yooj yim, cov khoom sib nqus tshwj xeeb, kev tiv thaiv corrosion, thiab lwm yam khoom siv hlau xws li weldability, kev kho cua sov, thiab kev ua haujlwm txias. Cov yam ntxwv ua tau zoo no ua rau cov hlau ntshiab muaj cov ntawv thov dav dav hauv ntau qhov chaw.
